MANURE-LOADER.

Specification of Letters Patent.

Patented June 2, 1908.

To all whom it may concern:

Be it known that we, JOHN D. RIETVELD, CORNELIUS DIELEMAN, and WIEGERTD. tIETvELD, citizens of the United States, residing at Pella, inthe-county of Marion and State of Iowa, have invented a certain new anduseful Manure-Loader, of which the following is a specification.

The object of our invention is to provide a manure loader of simple,durable and inexpensive construction in which the receiving and dumpingplatform may be placed in one position and a number of scraper loads ofmanure easily and conveniently deposited thereon and then the receivinganddumping platform may be elevated and the load automaticallydischarged into a Wagon adjacent thereto.

Our invention consists in the construction, arrangement and combinationof the various parts of the device, whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in our claimsand illustrated in the accompanying drawings, in Which Figure 1 shows aside elevation of the complete manure loader embodying our invention,the dotted lines show the receiving and dumping platform in position fordischarging into a wagon, and ldig. 2 shows a rear elevation of thecompletemachine embodying our invention.

Referring to the accompanying drawings, the base of the machine iscomposed of four runners indicated by the numeral 10. Secured to therear ends of these runners are the uprights 11 connected at their upperand lower ends by the braces 12. Secured to the forward ends of therunners are the short uprights 13, said forward ends of the runnersbeing connected by a cross brace 14. The rear uprights 11 are supportedin their upright position by the braces 15 and the short uprights 13 aresupported by the braces 16, thus forming a light yet strong frame forthe device. Mounted in the forward uprights 13 is a shaft 17 on which anumber of rollers 18 are mounted. At the top of the rear uprights 11 isa cross piece 18 having at each end two pulleys 19 and 20. At the bottomof two of the uprights 11 are the direction pulleys 21.

The manure receiving and dumping platform is supported upon arms 22having their rear ends pivoted at 23 to the outeruprights 11, said armsprojecting to a position beyond the front of the frame where they areconnected by a cross piece 241. Mounted on this cross piece are twopulleys 25 near each end. On the outer end portions of the arms 22, wehave fixed the manure receiving plat form 26. Pivoted to the arms 22adjacent to the cross piece 24 are the bars 27, to which a dumpingplatform 28 is fixed having the sides 29. The dumping platform isnormally held at an angle slightly greater than a right angle relativeto the receiving platform 26 by means of two jointedarms at the endsthereof. Each of said arms comprises a part 30 pivoted to the dumpingplatform and a part 31 pivoted to the arm 22. These arms are pivotallyconnected at their central portions by the bolt 32 and the part 31 isprovided with an extension 31 to overlap the part 30 and prevent thejoint that connects said parts from bending in a direction away from theextension 31, said extension, however, does not prevent said arms frombending at their pivot in a direction toward the receiving platform.Fixed to the ends of the cross piece 12 are two stops 33 in position tobe en-. gaged by the parts 31 as the platforms approach their dumpingposition.

We have also attached to one of the arms 22 a contractible coil spring33 the other end of which is attached to the central portion of one ofthe runners 10, said spring being so arranged that it will be undertension 'when the arms 22- are in dumping position and said spring is ofsuch resiliency that when the load has been discharged, the spring willmove the arm 22 to which it is attached to a position past a verticalline drawn through the pivotal point of the arm 22, so that thereceiving and dumping platform' may then automatically return by gravityto position for receiving a load.

e have provided for elevating the platforms as follows Two ropes orcables are provided, one for each end of the device, said ropes havingtheir ends connected to a swingle-tree 34 to which a draft animal may beattached. One of these ropes 35 is extended first under the pulley 21 atone end of the frame, then over the pulley 19 that is directly above it,then under one of the pulleys 25, then over the pulley 20, then underthe other pulley 25 and its end is attached to the part 18. The otherrope 36 is arrangedin a similar manner at the other end of the frame.For moving the loader from place to place, -We have provided chains 37attached to thecentral runners 10 and connected by a ring 38 to whichdraft animals may be connected. In practical use and assuming the deviceto be in the position shown in solid lines in Fig. 1, a load may bereadily and easily placed upon the receiving of a scraper or in anyother way. sufficient load has been placed thereon, a wagon ispositioned adjacent to the rear of the frame and the draft animalconnected with the ropes 35 and 36 is advanced. By having the ropespassed over the guide rollers l8 and then almost straight downwardly, itis obvious that the outer ends of the arms 22 are given almost a directupward pull so that less power is required for starting the load, thanthough the ropes passed direct from the ulleys at the upper rear end ofthe frame to t e outer ends of the arms 22. Furthermore by the pulleyarrangement shown and described, the power applied to the ends of theropes 35 and 36 is greatly increased as applied to the arms 22. When thearms 22 approach a substantially upright position, the load on thereceiving platform 26 is discharged upon the dumping platform 28, which,however, is held in position substantially at right angles to thereceiving platform so that the material will be retained in said dumpingplatform. Immediately after the arms 22 have passed a vertical line, thearms 31 will engage the stops 33 and thus remove the support for therear end of the dumping platform permitting it to swing to the positionshown by dotted lines in Fig. 1, so that its contents may be dischargedinto the wagon. As soon as the load has been discharged, he spring 33will return the arms 22 to a position in front of a vertical line andthey will descend by gravity to their starting position. By thusproviding means for automatically dumping the platform 28, it is notnecessary to move the arms 22 much beyond a vertical line so that themachine frame need not be as high nor the arms 22 as long as they wouldif the dumping platform were fixed in its position relative to thereceiving platform.

Having thus described our invention, what we claim and desire to secureby Letters Patent of the United States, therefore 1S- 1. In a manureloader, the combination of a frame, arms pivoted to the frame, areceiving platform fixed to the arms, a dumping platform pivotallyconnected with the arms adjacent to the receiving platform, jointedbraces for the dumping platform, means for jointly elevating the armsand means for breaking the joints of the jointed braces when theplatforms approach their dumping positions.

2. In a manure loader, the combination of a frame, arms pivoted to theframe, a receiving platform ed to the arms, a dumping platform by meansWhen a platform pivotally connected with the arms adjacent to thereceiving platform, jointed braces for the dumping platform, means forjointly elevating the arms and means for automatically breaking thejoints of the jointed "braces when the platforms approach their dumpingpositions.

3. A manure loader, comprising a frame, arms pivoted to the frame, areceiving platform fixed to the outer ends of the arms, a dumpingplatform pivoted adjacent to the receiving platform to normally standsub stantially at right angles thereto, jointed arms connecting thedumping platform and the said pivoted arms, said joints capable offolding in one direction only, means for elevating the pivoted arms andstops on the frame to engage the jointed arms when the platformsapproach their dumping positions.
